QIII4A(source port of quake 3)

Invalid date

Added ACCESS_SUPERUSER permission because some authors of Superuser apps think that it is clever to ask root permissions twice (but I think that it is the most stupid idea I've ever heard).
Replaced one-time donate notification with bottom offline ad: 4 (for each port) one-time notifications are quite annoying.
A bit more friendly to users that don't read the description.
Updated engine and GCC used to build it.
